Migration basics

The migration process involves compiler migration (recompiling source programs with the Enterprise COBOL for z/OS® compiler) and might involve a runtime migration (moving your applications to z/OS Language Environment®) as well. As part of the migration process, you will also need to do inventory assessment and testing. As stated previously, you are not required to do your recompilation and runtime migration concurrently.

For more details about the migration process, see General migration tasks.
